Which of the given statement is not true ?

Options

A. Copper pyrites also contain in `FeS_(2)
B. Zinc blende mainly contain zinc chloride
C. Gold is found in native state
D. Sliver glance mainly contains silver sulphide

Answer

To solve the question "Which of the given statement is not true?", we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "FeS2 is present in copper pyrite."
- **Analysis**: Copper pyrite, also known as chalcopyrite, has the chemical formula CuFeS2. It does contain FeS2 (iron disulfide), so this statement is **true**.

- **Statement 2**: "Zinc blend mainly contains zinc chloride."
- **Analysis**: Zinc blend, also known as sphalerite, primarily consists of zinc sulfide (ZnS), not zinc chloride (ZnCl2). Therefore, this statement is **false**.

- **Statement 3**: "Gold is found in native state."
- **Analysis**: Gold is indeed found in its native state due to its low reactivity and is one of the least reactive metals. Thus, this statement is **true**.

- **Statement 4**: "Silver glands mainly contain silver sulfide."
- **Analysis**: Silver glands, also known as argentite, is primarily composed of silver sulfide (Ag2S). Therefore, this statement is **true**.

2. **Conclusion**:
- After analyzing all statements, we find that the only statement that is not true is **Statement 2**: "Zinc blend mainly contains zinc chloride." The correct composition of zinc blend is zinc sulfide (ZnS).

### Final Answer:
The statement that is not true is **Statement 2**.
